JULIUS MATZKE, OF INDIANAPOLIS, INDIANA.

STEAM' WALL-PAPER REMOVER.

Application filed March 8, 1916.

To all whom it may concern:

Be it known that I, JULIUS MATZKE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements inSteam VVall- Paper Removers, of which the following is a specification.

The object of this invention is to provide a convenient means for utilizing live steam for reducing the adhesive action of the paste by which paperdecorations are made to adhere to walls, in order to make easy the removal of old paper preliminary to redecorating.

The object also is to so localize the application of the steam as to avoid injury to adjacent wood-work or other accessories, and a further object is to exterminate all germ and insect life on the wall or in its crevices by the action of the hot steam.

I accomplish the above and other objects which will hereinafter appear, by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective View showing my invention in actual use. Fig. 2 is a section on the line 22 of Fig. 4, in crosssection of the steam-applying head and longitudinal section of the supply pipe leading thereto. Fig. 3 is a cross-section on the line 33 of Fig. 4:. Fig. 1 is an under-side view of the steam-applying head looking into its hollow interior. Fig. 5 is a view in crosssection of a nozzle attachment for reducing the normal discharge area of the head. Fig. 6 is a like view of the nozzle and head assembled, and Fig. 7 is a side view of said assembled parts.

Like characters of reference indicate like parts throughout the several views of the drawings.

The live steam is supplied from any suitable source, as from the radiator 8, in steamheated apartments during those months of the year when the radiators are supplied with steam, and at other times, or in places which are not equipped'with steam heating apparatus, the steam will be supplied from a small portable boiler of any usual and suitable construction (not shown).

Steam from a source as above provided for is supplied through a flexible pipe or hose 9, preferably having a valve 10 where it attaches to the radiator by first removing the usual ventilating valve. The other Specification of Letters Patent.

Patented July 4, 1916.

Serial No. 82,818.

end of the hose is connected with a rigid metal pipe 11, which enters a hood-shaped head 12 and discharges into the middle of a distributing compartment 13, extending longitudinally the full length of the head. The sides of the head are made out of sheet metal in semi-cylindrical form open across the full diameter of the cylinder for the free contact of the steam, entering the head through perforations 1% in the pipe 13, with the papered wall to be treated. The perforations 14 are preferably in two or more rows and staggered, as shown, to distribute the steam as thoroughly as possible. The ends of the head are closed by walls 15. Outside flanges 16 are provided along the longitudinal edges of the head to retain a nozzle 17, having a reduced discharge 18. The corresponding edges of the nozzle are bent to form hooks 19, which receive the flanges 16, 16, with an end-wise sliding fit for the assembly or removal of the nozzle as the work in hand may require. Supports for a handle 20 extend from the pipe 11 and head 12, and 21 is abrace from the outer end. of the pipe 11 to the head. A valve 22 at the outer end of the pipe provides conveniently located means for controlling the steam supply to the head. For flat and extended surfaces the full opening of the head is desirable, but for working close to wood work and for discharging steam into crevices to kill vermin, the nozzle attachment is recommended.

My head and attachments are of sheet metal and light parts which enable them to be operated with one hand, leaving the other hand of the workman free to use a scraper in removing the paper as it is loosened by the steam. The movement is preferably from the top down, and after a first strip is removed like A in Fig. 1, the successive strips are more effectively loosened by allowing the head to project over upon the space A sufficiently to allow the steam to work in under the edge of the paper to be loosened.

WVhile I have described my invention with more or less minuteness as regards details of construction and arrangement and as be ing embodied in certain precise forms, I do not desire to be limited thereto unduly or any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, construction and arrangement, the omission of immaterial elements and the substitution of equivalents as circumstances may suggest or as necessity ma render expedient.

I claim 7 1. A means for applying steam to papered walls to loosen the paper therefrom for removal comprising a hood-shaped head of greater length than width having a longitudinal opening, a steam distributing means extending longitudinally of the head the walls of the head converging fro-m its longitudinal edges toward said distributing means, means for supplying steam to said distributing means, comprising apipeparallel with the longitudinal opening 1n the head, a valve in the pipe for regulating the steam flow through it and a handle attached to the pipe between the valve and said steam distributing means.

2. A means for applying steam to papered walls to loosen the paper therefrom for removal comprising a hood-shaped head of greater length than width having a longitudinal opening which is closed by the wall While the head is in use, outside flanges on the longitudinal edges of said opening, means for varying the size of said opening comprising a nozzle having edges bent to form hooks which receive said flanges by an end-Wise sliding movement, a steam distributing means extending longitudinally of the head, the Walls of the head converging from the longitudinal edges of said opening toward said distributing means, means for supplying steam to said distributing means, and means for regulating the steam supply. In witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this 21st day of February, A. D. one thousand nine hundred and sixteen.
